SubjectDhcp: Ip length 44 disagrees with bytes received 46.
Date
Hi lkml!

Maybe it's not good to ask the lkml, but since there are so many experts
here, it makes sense to me.

I have a dhcp-server running with 2.6.10 (had it running with
2.6.{1,2,3,4,5,6,7,8,9} as well) and the dhcpd logs all the time:

Now my question; Is this normal? Where does it come from? Why does it
happen? For me this seems strange...

FYI. I have the server running with the above mentioned kernel and Fedora
Core Development Tree (dhcpd 3.0.1).

Any help is welcome!

Best regards,
Oliver
